f l'o Vall whom 'it may concern:

Be it known that I, WILLIAM MARION MURRAY, a citizen of the UnitedStates, and

description.

la resident of Sawtelle, in the county of Los ngeles and Statel ofCalifornia, have invented a new and Improved Oil-Spreader, 'of which thefollowing isa full, clear, and exact This invention relates to oilspreaders, and is particularly useful in connection with devices of thischaracter used for the purpose of incorporating oil, tar, asphaltum andthe like with the earth or other material of roads.

An object of the invention isto provide an oil lspreader of simple,strong and eflicient design, by means of which the oil or other fluid isa'tomized and forced into the roadway at an appreciable distance belowthe surface of the same.

A further object of the invention is to provide a device of thischaracter by means of which the oil, tar, asphaltum or other fluid,

is thoroughly atomized by means of a steam or compressed air spray andis 'ejected from an adjustable 'plow arranged to `be forcedlongitudinali under the loosened material of the road, an which`isprovided with a roller ada ted thoroughly to mingle the earth and 'fluiafter the plow has passed through the former. l

A still further object of the inventionis to provide an oil spreaderhaving a low arran ed to be forced longitudinally allong ythe roar at anappreciable distance .below the surface of the same, having means forermittin the escape of the atomized oi or other uid at the rear of theplow, and also having a device for regulating'the passing of theloosened road material over the plow, whereby the admixture of theatomized fluid with the material can be controlled. v d c Another objectof the invention lis to provide an oil spreader including, a" wheeledframe carrying a low which serves to loosen the road materialpandpermits the escape of the atomized oil or other fluid .therefrom to thematerial, and s o arranged that the lvarious operable parts of. thedevice are driven by power derived from the movement of the wheeledframe.

The invention consists in the construction and combination of parts to"be more fully described hereinafter and particularly set forth in theclaims. i

Before` proceeding to a more detailed explanation of. my invention, itshould be unsimilar substance, is incorporated into the material of theroad for the purpose of rendering the saine compact, and to a certaindegree impervious to moisture. At the same time, the 1m regnation of theroad with the oil or other uid, to a large extent obviates T-o carry outthe process of 'incor oratinvthe oil, 'tar or asphaltum with the c irtor other material of t usually plowed or harrowed to a certain depth andthe lum s of earth are broken up as finely as possib e, manually or insome other suitable manner. By means of 'my invention, the fluid ismingled with the earth' of the road and incorplorated with the sameunder the lsurface of t e roadway, b means of a plow which travelslongitudinal y under the surface of the road and through which the fluidis ej ected; It is ofcourse ofimportance that the fluid be sprayed not-merely u on the surface of the earth but be thoroug y lmingled withthey earth ofthe roadway. p Mv invention.y effects not only this, but'as well"v obviates the preliminary work of plowing or harrowing theroad and breaking up thema-l I employ steam or compressed air'to terial.atomize the oil, tar or 'asphaltum`, and Vin this way the articles ofthe Same are thoroug'hl e road, the latteris scattere and mingled withthe loosenedsoi ,I v which is suitably.workedupby a toothed y roller,lwhich follows theplo'w andisoperated by the movement of thewheeled framewhich carries the plow. y At the same time the passing ofthe lmaterialover the plow v[isfregulated by means of a belt with blades, which is oerated by the lmovement of lthe yframe and wlhich serves to regulate theadmixture of the ment, the sprocket wheel 15, which is coni so -.-L-stoo that the pump is operated by the 1 movement ofthe device itselcating with the pump cylinder 9.

fluid with the earth, the speed of the device along the road controllingthe operation of the.- admixture regulating. mechanism. 4

Referring more particularly to the draw- 5 ings,'I provide a wheeledframe 1, which is constructed to travel upon the road-as is an ordinaryvehicle. The frame 1 comprises substantially horizontally supportingmembers 2, carried by the front'axle 3 and the rear axle 4, mounted insuitable brackets attached to the members 2. Mounted upon the frontaxle- 3 are the-front wheels 5, and mounted upon the rear axle 4 arethelrear wheels 6. The su porting members 2 are transverselybracedp yproper tie members 7 and 8, riveted in osition and consisting preferablyof charme s, Arranged u on thesu porting members 2 is a pum cy inder'9,t e

piston 10 of Which is pivota ly secured to a crank disk 11, mounted witha sprocket wheel 12 upon a transverse shaft 13, journaled in vsuitablevbearing brackets 14^upon the supporting members. Loosely mounted uonthe rear axle 4 is a second sprocket wheel 15, having a rigid clutchsectionpl. A second clutch `section 17 arranged to engage the section16, is slidably mounted upon the axle 4 and is arranged to rotatetherewith. lIt will be understood that when the sections 16 and 17 `arebrought intooperative engagevnected by means of a chain 18 with thesprocket wheel 12, revolves with the axle 4 and through the chain andthe sprocket Wheel on the axle 13 drives the ump.' An 'annular guidemember 19, is slida ly mounted'upon the axle-4 and isarranged to rotatej therewith. The member 19 is secured to the 'clutch section 17 and isadapted to operate thesame. An arm 20, at oneend engages the-annularmember 19 and at the other end is secured to-a bell crank lever 21mounted on va transverse member 22' of the frame, the ,other end of the.bell crank lever being se.- cured to aQlink 24. The link 24 is pivotallylattached to" a lever 2'5, which can be manually operated and. by meansof which the clutch sections'can be thrown into engagementto drive thepump, or separated to stop the o eration of the same. A It will beundery upon the road- "way, the s rocket wheel 15 being driven from therear'w eels'of the vehicle, as 1t is mountedv upon the axle of saidwheels.

A ipe 26, is mounted upon the supporting me'rniers2 and has a branch 27,communiside of the connection of the pipe 26 and the branch 27 arevalves 28 and 29, controlling the operation of the ump and serving todirect the fluid* force b `the pump, in the roper direction, as W' apear hereinafter. `he pipe'26 has a flexible tu' e connection 30,

v with a supply tank which can be-drawn upon -end of the device.

On each r another vehicle or be elsewhere suitably carried. The pumpdraws the oil or other fluid from the tank through the pipe 26 andforces it along the same to a tube 31, joined to the end of the pi e andcommunicating with a 7 transverse cy inder 32, located at the rear Thearrangement of the valves 28 and 29 is such, that during a suctionstroke of the pump the valve 29 is closed and the valve 28 is opened. On-the return 7 stroke of the pum rwhich forces the fluid from thecylinder, t e valve 28 is closedand the valve 29 is opened, therebypermittin the flow ofthe luid to the cyllnder 32 an( preventing thereturn of the fluid along the g pipe 26. Y

Carriers 33, preferably comprising similar longitudinal channel barsarepivotedtto the forward axle 3 by means of a suitable bracket 23. jThe carriers 33 are inclined at an a le with the ground, and have therear ends dlsposed parallel to the ground and extending under thetransverse cylinder 32.- A cross member 34 is secured near the rear endsof the carriers 33 and has the extremities up- 9 wardly disposed to formu rights 35, which are rovided with lateral anges 36. Preferab y, thetransverse member and nthe u rights 35 are formed from a single,suitabl;r bent channel. The uprights 35 are located y9 slidablyinbrackets 37, provided at the ends of the tie member 8.' 1 "lhe flanges36 lof the uprights are provided at the edges with a p urality ofnotches 38, adapted 'to' engage with pins 39, locatedl in openings ofthe 1 brackets 37. By means of the notches 38 and the pins`39, theuprights can be secured to the tle member 8 1n a'plurality of4positions, whereb the height of the carriers above the roa -bed can beregulated and ad- 1 justed as desired. .I

Rotatably mounted in proper journal brackets 40, carried at the ends ofthe members 2, is a transverse shaft 41 having .a controlling hand-wheel42 and a ratchet 43 en- 1 gaging with a pawl`44 mounted upon one of thejournal brackets. W oiind upon the shaft 41 near the ends of the sameare chains 45, secured to extensions 46 rigid with 'the uprights 35. Byturning the shaft 41 by means of the hand Wheel 42, the carriers 33 can.be raised or lowered `as desired, to adjust their height vabove theroadway. A shaft 47 atisubstantially right-angles to the transverseshaft 41, and provided at its up- 1 per end with afcontrollinghand-wheel 48.and at its lower end with a drum 49, is rotatably mountedat the rear of the frame in journal brackets provided for the purpose.Wound about the drum 49 is a chain 50, having its 1 extremitiesrespectively secured to the op osite carriers 33. By turning the shaft47}l)y means of the hand wheel 48 in one direction or the other, thecarriers 33 can be adjusted laterally as conditions require. The shaft47 1 the uprights 35, and consists has a toothed or serrated Wheely 47arigidV therewith, and adapted to engage a dog 47", which thereby locksthe shaft against a movement of rotation.` ,When it is desired to lowerthe carriers 33, it is necessary to displace thepawl 44 to permit theshaft 41 to rotate. Similarly, when it is desired toV turn the shaft 47in one direction or the other, the dog 47b must be disengaged from thetoothed wheel 47 a. Y

A transverse beam V51, is rigidly secured to rcferably of an anglemember and carries t 1e plow supports 52', which depend therefrom andare secured thereto in any suitable manner. The plow supports 52 arehollow and open at the rear, havin theforwardportions wedgeshaped tofaci 'tate their passage through the materialof the road. At the loweredges `thiy are provided withlaterally disposed vfflangesz' 53, for apurpose which will appear hereinafter.- `A cover 54,`is arranged at thetop'of the plow-sup orts, and extends between the same and t etransverse beam 51s The plow supports 52 are inclined forward asv isshown most clearlyin Fig. 4, this inclination serving to facilitate themovement of the supports through the material of the roadway. As theedge of each of the plow supports is disposed toward the direction ofmotion of the device, the sup orts can move easily through the looseneearth of the roadway. The plow`55 is arranged transversely of thedevice, and is wedge-shaped in' form with a horizontal edge extendingtoward the frame of the device. The plow comprises a solid body 56,having a substantially horizontal lowerface 5-7, and an yinclined toplate 58, having the lower edge beveled to ferm the cutting orforwardedge of the plow, .At the rear, the 'body of the plow is cut away andreceives a hollow movable member 59. The top plate 58 hasopeningsfformed therein to receive the laterally disposed flanges 53 ofthe` plow supports. The flanges 53 engage at the under side of the topplate 58 adjacent to the edges of the openings, and are secured tothetop plate by means of rivets 60'. Within-the plow supports 54 are oilducts 61, which communicate with the cylinder 32 andhave the lower 55.flexible covers 63, consisting, or instance, of

' endsarranged within the openingsv of the top .plate 58. The movablemem er l59has chambers 62 therein, extending the entire length of themember and rovided with diaphragme of cop er plate Vor thelike. The

. open lower ends o the ducts 61 are arrangedl at suitable openings ofthe coversy 63,l and tliereb the flow of oil from the cylinder throngthe ducts 61 to the chamber 62 is` edected. A slot or openin 64, isformedat the rear of themember 59; etweena lip 65, and a movable bar66,.which is secured to the exibleucover 63. Set screws 67 arranged theopenings 69 intersect the stream of -oil flowing from the slot andatoinize the saine.

Within each of the ducts 61 is located asteam pipe 70, having the loweror discharge vend arranged in an o ening 71, communicating with thesteam ciiamber 68. 'lhe steam pipes 70 extend upwardly and communicatewith a common steam i e 7 0a to which the steam may be 'admittei lymeans of a pipe 7 0b. It will be understood that compressed air can beused as well as steam. The steam pipes 70 extend through openings in thecy inder 32 and pass through stuffing boxes 72 of the usual form andincluding glands 73 and adjusting screws 74.

The discharge openings of the oil chambers and the row of openings ofthe steam chambers extend substantially the entire length of the plow,and are so arranged that the oil and steam or compressed air esca ingtherefrom mingle a short distance behin the plow, the vapor atomizingthe li uid and causing the vsame to permeate t e earth which falls overthe-rear edge of the u per plate 58 of the plow as the latter moves aong under the loosened road lmaterial.

At the rear edge of the cover 54 is a transjverse angle member 75 towhich is secured an apron 76, extending backwardly and downwardly towardthe road and having Sides 77. Underneath the apron is mountedA a roller78, carried upon a shaft 79, journaled in bearing brackets at the sidesof the apron. The roller 78'has radial projections or teeth wise workthe' material of t e roadway at the backof the plow. 'At one side, theroller has av pulley '81, which is operatively connected by means of abelt 82, with a pulley 83, rigidly mounted u onV the axle 4, so that theroller isoperated )y the forward movement of the vehicle along theroadway.

A transverse shaft 8.4, is' arranged above the .plow 55, and-hastheextremities jourlnaled in suitable bearings 85. Rigid with thebearings are posts 86, extending through openings in the'cover 54 andpassing through sockets 87. The Aposts 86 are movably mounted within thesockets and have rigid collars 88. The posts 86 at the, upper 1inopenings of the lip 65 and the bar 66, er-

consequently, the steam jets escaping from 80, which serve to break ulevel and otherwhichI are alinedA with similar wheels 94,

operately connected by means of a chain 91,

with a sprocket 92, mounted u on the axle 4 at the outside of a wheel 6;hus theshaft 84 is driven by the forward movement of the wheeledframeupon the roadway. Between each pair of adjacent plow su ports 52,the shaft 84 carries-separated toot ed wheels. 93,

mounted u on a transverse shaft 95, carried inV 'ournal rackets 96,attached tothe up` rig ts l Chains 97,'-are arranged upon the alinedtoothed wheels 93-and 94, and have brackets 98 which carry transverseblades or paddles 99,' extendingfrom chain to chain of aach pair betweent e adjacent plow supports. e y ,I V

rlhe chains and pedals .constitute a device for regulating the.admixture of the -atomized oil or other fluid withthe earth, for thepaddles are so' arranged that they control the assage of'the loosenedearth over the plow. h paddles are-driven over the plow toward the rearedge of the same and thus force the earth along the top plate and overthe plow. The faster the vehicle travels the faster will the'- addlesmove, and consequently the more rapldly will the earthbe forced over theplow `and to the 4rear of the same. AItwjll be understood that if theearth passes slowly over the plow a greater quantity. of oil will be Vfmixed with the earth erV unit mass of the same; consequently, 'thevehicle travels more rapidly the earth is moved over the plow muchfaster and less oil is forced into the same. Onvthe other hand, when thevehicle moves more slowly, the earth passes over the plow more slowlyand a greater quantity of oil per .unit mass of fearth, is incorporatedl in the material of the roadway:v
